LAMP-BURNER.

BPECIFICATION forming part of Letters Patent No. 341,018, dated May 4, 1826.

Application filed April 18, 1885.

To all whom it may concern:

Be it known that I, GEORGE KELLY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Inr proveinentsin Lamp-Burners, of which the following is a specification, to wit:

This invention relates to lamp-burners; and it consists in certain peculiarities of the construction and arrangement of the same, substantially as will be hereinafter more fully described, and set forth in the claims.

In order to enable others skilled in the art to which myinvention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the accompanying drawings, in which Figures 1 and 2 represent side elevations of my burner, and Fig. 3 a vertical section of the same. Figs. 4 and 5 are central vertical sections. 7

a represents the screw-threaded base of a lamp-burner, to which is attached the perforated diaphragm a, of any desired form, formed with an elongated slot, a in which the upper end of the wick-tube is held, and which allows this tube to be moved to one side or the other to regulate the flame and prevent its smoking. In lamp-burners of this nature it has been difficult to hinge or pivot the wicktube on account of the limited space in which its lower end must be set, and the difficulty of attaching a pivot at that point. To obviate this I place around the tube a spiral spring, b, the lower end of which rests upon thescrewbase of the burner at the center of the tube, and acts as a pivot, upon which said tube is moved back and forth.

Upon the upper end of the tube,beneath the diaphragnnis placed a plate or collar, 2), which is preferablyperforated to permit the free passage of the air to the flame, and against which the upper end of the spring bears to press it against the diaphragm and produce sufficient friction to retain thetube in the position desired. It will be seen that the tube rocks freely upon its pivotal spring, and can be adjusted to one side or the other to regulate the flame and produce an even combustion should the wick be irregularly trimmed.

In Fig. 3 is represented a common burner, and in this the lower end of the spring is sol- Serial No. 102,708. (No model.)

dered to the tube, to prevent the latter from slipping down, and as the tube is closely held in the screw-base it is not necessary to secure the end of the spring to the base, though it may be done, if desired, as in dotted lines in Fig. 3. on account of the reaction of thcspringagainst the collar and diaphragm.

In Figsl and 2 is represented the same mode of hinging the tube applied to a burner, in which the tube is capable of being pulled down to light the lamp without removing the chimney. In this case the lower end of the spring is not secured to the tube, in order that the latter may be free to slide vertically; but the upper end of the spring bears against the collar, (which is secured,) or against a projection or shoulder on the tube, to sustain the latter and produce sufficient friction between the collarand diaphragm to retain the adjustment, as desired. In this burner two arms, (I, are attached to the tube to pull it downward, which slide in guide-slots (Z in the frame, and these slots in Fig. l are formed with lateral extensions (1 at the upper end to permit the rocking of the tube, while in Fig. 2 these slots are reversed, being placed in the arms (I, to produce the same effect.

In any case, no matter what may be the shape or kind of burner used, the lower end of the pivotal spring rests on the screw-base at the center of the tube, and the upper end presses against a collar or shoulder on said tube, which is thereby pressed into frictional contact with the diaphragm, and the latter is slotted to permit the tube to be moved.

The adjustment of the wicktube is very easy, though positively held when made, and where lamps are out of easy reach the adj ustment is easy wit-h the aid of a stick or other similar device, which cannot be done in the ordinary manner of adjusting these tubes by screws, and the collar forms a cover for the slot, making a much more sightly and finished article.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a lamp -burner having the usual openingin its base for a wicktube, a slotted diaphragm above said base, with an opening of greater extent than the width of The tube cannot lift out of the base,

the wick-tube, and a wick-tube loosely mounted in said base and diaphragm, of a spring with its lower end resting on the base of theburner and its upper end connected with the wicktube, substantially as shown and described, and for the purpose set forth.

2. The combination, with a lamp burner having a transversely-slotted diaphragm and a wick tube loosely mounted in said diaphragm, of a collar placed on said tube and a spring bearing against the collar, to press it against the diaphragm and retain the adjustment of the tube, substantially as and for the purpose set forth.

8. The combination, with a lamp burner provided with aslotted diaphragm and a loosely mounted wick-tube, of a collar on said tube and a spring surrounding the same, with its upper end pressing against the collar and its lower end resting on the base of the frame at the center of the tube to form a pivot for the same, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE KELLY.
